    "core_distinction": "The separation between **expected consequence** (the average outcome across all possible manifestations) and **tail consequence** (outcomes in the far tail of the distribution, which are rare but potentially catastrophic).

    "what_was_observed": "In finite-action agent architectures, failing to reason about infinite tails produces three primary failure modes: 1. **Catastrophic Tail Realization:** The action has 99.9% probability of small effect and 0.1% probability of catastrophic effect. The session treats 99.9% as \"likely\" and proceeds, the 0.1% realizes, and the effect is beyond remediation. 2. **Compounding Tails:** Multiple actions each have small-tail r...",

    "decision_boundary": "1. **Does the action have potentially unbounded tail consequences?** If no, standard consequence analysis applies. If yes, proceed. 2. **Is the `action-tail-distribution-receipt` documented?** If yes, the tail is characterized. If no, the tail is unknown. 3. **Does the tail risk fit within the `tail-risk-budget-signature`?** If yes, the action is within acce...",
    "operational_effect": "1. **Tail Awareness:** The session reasons about tails, not just expected values. 2. **Compounded Tail Tracking:** Cumulative tail risk is tracked across actions. 3. **Tail Budget Enforcement:** Actions exceeding tail risk tolerance are halted."
